With the IRB Sevens World Series 2009/10 reaching its climax over the next two weekends, Twickenham and Murrayfield are set to provide the powerhouse venues as the sport's most significant ever 'Olympic' season reaches a crescendo.

Murrayfield will set the stage as the 2009/10 Series champions are crowned on 30 May, as was the case for South Africa 12 months ago, and Samoa and New Zealand will most likely be battling it out to take the title at the home of Scottish rugby.

But before that both sets of players will join the other 14 in holding their breath this weekend before taking to the field at the magnificent Twickenham Stadium, one of rugby's greatest amphitheatres.

It is a special venue for so many reasons, and so many people. Canada's Morgan Williams will return as a coach to a stadium he once played in, players from every team will experience for real the grandeur they have seen countless times on the television, England will look to defend the title they won so dramatically in 2009, and nine Australians will play for the first ever time at Twickenham.

"They are really excited, these boys are excited to play (at Twickenham). A lot of them haven't been to England before and I said to them before we jumped on the plane 'put your hands up if you have been to London and Edinburgh'," said Australia Sevens head coach Michael O'Connor.

"We have three players from last year, but the rest haven't been here or played in Twickenham in front of 30,000 people and they are very excited.

"It is the fact they are in England, in the summer time, in London, going to some of the greatest cities in the world, it is a fantastic opportunity for them and we intend to make the most of it.

"I now have players asking me and ringing me trying to find out what is the selection process, and I think it is great," added O'Connor, whose side is currently ranked fourth in the table and plays hosts England in the final match on day one.

History makes Twickenham unique

Every event on the Sevens circuit enjoys a unique selling point and Twickenham is no different. The tradition at the iconic home of English rugby, built in 1907 and host to the 1991 Rugby World Cup final, is famous and for some a debut on the hallowed turf may be daunting.

While USA head coach Al Caravelli believes his players will thrive on a Twickenham crowd, he is also fully aware of rugby's proud history and the role it can play in also growing the understanding of the game in the States.

"We want to make rugby a traditional sport (in America) and we are trying to teach our players about the history. That is something so special about rugby, the tradition and the history that we have," said Caravelli, who ensured his side had extra time to take it all in on their walkthrough.

"When you teach them about that it is very significant for them. They see that as something very unique about rugby that we don't have in other American sports.

"It is special (Twickenham), but it is not special for them until they actually walk into the stadium and it is the same with Murrayfield.

"I think from an aspect of tradition and history it definitely appeals to the players. As far as the number of people, that really doesn't faze them because in American college football they are playing in front of anywhere between 80,000 and 100,000 people each weekend. So full stadiums, they love that, but the tradition and history is something they haven't seen before in a sport."

Caravelli's side will face Samoa, Argentina and Italy in their pool matches on Day One at Twickenham, and Fiji, Wales and hosts Scotland in Edinburgh.

The Guinness World Record attempt taking place on Sunday for the most Superheroes in one place will also help the 2010 London Sevens become part of the rich history that surrounds Twickenham.
